I'd say it's subset of perfect solution fallacy [1]. Every edge case is seen as a problem that has to be solved, at any cost. One of the root causes is that when you're designing something, you really suck at understanding costs of your solution. To you, the cost either seems close to zero (because you are familiar with your own solution), or cost doesn't matter because you think you're solving problems that are essential to domain. Somewhat counterintuitive, the more senior folks are, the more likely they are to be affected by it. [1] https://en.wikipedia.org/wiki/Nirvana_fallacy https://en.wikipedia.org/wiki/Nirvana_fallacy
